enantiomer,

another term for optical isomer. See Stereoisomers under isomerisomer
, in chemistry, one of two or more compounds having the same molecular formula but different structures (arrangements of atoms in the molecule). Isomerism is the occurrence of such compounds. Isomerism was first recognized by J. J. Berzelius in 1827.

When polarized light passes through a solution containing an enantiomerically pure compound, the light emerges with its plane of polarization changed.
They were able to introduce a chiral twist into these materials by inserting an enantiomerically pure (one-handed) chiral monomer, such as indane bisphenol (IBP) or spirobiindane (SBI), into the polymer backbone.
Thus, chiral drugs extracted from plants and animals are enantiomerically pure.
The study of stereoselectivity has evolved from issues of diastereoselectivity, through auxiliary-based methods for the synthesis of enantiomerically pure compounds (diastereoselectivity followed by separation and auxiliary cleavage), to asymmetric catalysis.
In this project, we propose to develop an industrially scalable, practical method for the synthesis of a-arylated quaternary amino acids in enantiomerically pure form by streamlining, optimization and scale-up of a reaction we discovered while working on the synthesis of quaternary amino acids as conformational controllers within an ERC-funded Advanced Grant.
As is well known, discovery of the existence of enantiomeric isomers of organic compounds as well as their isolation as enantiomerically pure isomers with the use of tweezers under microscope were performed for the preparation of enantiomerically pure D-(-)- and L-(+)-tartaric acids as early as the mid-nineteenth century by L.
